In the food processing industry, customers often ask:

Are "spiral towers" and "spiral freezers" the same thing?


In fact, they are related but also different. Let's take a quick look today.


1. What is a Spiral Tower?


A spiral tower is essentially a conveying device consisting of multiple layers of spiral mesh belts, enabling long-term product transport within a confined space.


Common Uses:

  • Cooling bread and pastries

  • Buffering and conveying cooked food

  • Product shaping and queuing


In other words, a spiral tower isn't designed to freeze food per se; it's more like a flexible conveyor line.

2. What is a Spiral Freezer?


A spiral freezer is a spiral tower with a refrigeration system and insulation structure added.


Its core function is to rapidly freeze large quantities of product within a confined space. Typical applications include:

  • Chicken, beef

  • Steamed buns, dumplings, pastries

  • Seafood


Compared to linear freezers, the biggest advantages of spiral freezers are: a smaller footprint, higher production capacity, and suitability for continuous production.

3. The Relationship Between Spiral Towers and Spiral Freezers


It can be understood as follows:


  • The spiral tower is the "body," providing a multi-layered spiral conveying structure;

  • The spiral freezer is a spiral tower with a "heart and blood circulation" (refrigeration system and insulation system), giving it the ability to freeze quickly.

  • Thus, the spiral tower can be used independently, but once combined with a refrigeration system, it becomes a true spiral freezer.


4. How to Choose Spiral Towers and Spiral Freezers?


If you only need product cooling, conveying, and temporary storage, a spiral tower is sufficient;

If you require efficient and stable large-scale freezing, a spiral freezer is your best choice.
